A power point presentation on pollution, its various types and some incidents relating to pollution. An attractive presentation that will surely gain attention.POLLUTION IS THE ADDITION OF ANY SUCH CONSTITUENT TO AIR ,WATER OR LAND WHICH DETERIORATES THE NATURAL QUALITY OF THE ENVIRONMENT 3. AIR POLLUTION IS THE DEGRADATION OF THE AIR QUALITY HARMFULLY AFFECTING THE LIVING ORGANISMS AND CERTAIN OBJECTS

AFFECTING THE LIVING ORGANISMS AND CERTAIN OBJECTS

7. Fine particulate matter (PM2.5) is an air pollutant that is a concern for people's health when levels in air are high.
These particles come from coal plants and vehicles, and, at high levels, have been linked to serious respiratory
problems. Estimates of PM2.5 concentrations across India………………

9. SOURCES
NATURAL MAN-MADE

10. NATURAL SOURCES :-BEYOND HUMAN CONTROL,WILL CONTINUE TO OCCUR
MAN-MADE SOURCES :- VEHICULAR ,INDUSTRIES ,BRICK KILNS,GARBAGE,
THEY ARE UNDER HUMAN CONTROL TO A LARGE EXTENT

11. VEHICULAR AIR POLLUTION ……
-THE EXHAUST GIVEN OUT CONTAINS THREE MAIN GASEOUS POLLUTANTS i.e CO2,
SO2 AND CO
-WEARING OF RUBBER TYRES OF THE AUTOMOBILES RELEASING RUBBER PARTICLES.
-SPEEDING VEHICLES RAISE THE ROAD DUST PARTICLES INTO AIR.

13. INDUSTRIAL AIR POLLUTION
-CHIEF INDUSTRIAL GASEOUS POLLUTANTS: CO2 ,SO2 AND CO & OXIDES OF N2
-SMOKE RELEASED BY FACTORY CHIMNEYS CONTAINS LOT OF PARTICULATE POLLUTANTS

15. BURNING GARBAGE
-ON BURNING GARBAGE RELEASES CO2AND SOME OTHER HARMFUL GASES.
-SMOKE GIVEN OUT ADDS TO PARTICULATE AIR POLLUTION.

17. BRICK KILNS
-FIRE HEATING ENCLOSURES USED FOR MAKING CONSTRUCTION BRICKS.
-RAW MOIST CLAY BRICKS ARE ARRANGED IN HEAPS WITH FIRE WOOD IN BETWEEN AND THEN
COVERED BY SOME SPECIAL MUD MIXTURE TO CONTAIN THE BURNING FLAMES INSIDE.
-THE WASTES PRODUCED ARE LARGE QUANTITIES OF ASH AND BROKEN BRICK BITS.

28. It is considered the largest accidental marine oil spill in the world, and the largest environmental disaster
in U.S. history. Deepwater Horizon semi-submersible Mobile Offshore Drilling Unit (MODU) was about 40
miles (60 km) southeast of the Louisiana coast. The blowout and oil spill on the Deepwater Horizon in
the Gulf of Mexico wascaused by a flawed well plan that did not include enough cement between the 7-
inch production casing and the 9 7/8-inch protection casing.

30. Cultural eutrophication is a form of water pollution. Cultural eutrophication also occurs
when excessive fertilizers run into lakes and rivers. This encourages the growth of algae
(algal bloom) and other aquatic plants. Following this, overcrowding occurs and plants
compete for sunlight, space and oxygen.

32. Soil pollution comprises the pollution of soils with materials,
mostly chemicals, that are out of place or are present at
concentrations higher than normal which may have adverse effects
on humans or other organisms.

39. RADIATION

40. RADIATION IS A FORM OF ENERGY CONSISTING OF HIGH ENERGY PARTICLES.IT IS
USED EXTENSIVELY IN THE FIELDS OF MEDICINE AND IN GENERATING ELECTRICITY
IN NUCLEAR POWER PLANTS.

46. 1.ACID RAIN

50. Vehicular standards
-The Bharat Stage (BS) norms are emission control standards introduced by the
government in 2000 to keep a check on air pollution.
-Based on the European regulations (Euro norms), these standards set
specifications/limits for the release of air pollutants from equipment using internal
combustion engines, including vehicles.

51. -Typically, the higher the stage, the more stringent the norms. The current norms in India
are BS IV in 33 cities and BS III in the remaining country.
-Implementation of the BS V standard that was earlier scheduled for 2019 has now been
skipped. BS VI, originally proposed to come in by 2024 has been now advanced to 2020,
instead.
